Yokogawa EJA110E Differential Pressure Transmitter

This Yokogawa EJA110E is a standard differential pressure transmitter of EJA-E series, adopting Yokogawa patented single crystal silicon resonant DPharp sensing technology. It is used to measure differential pressure of liquid, gas and steam, and can realize flow calculation, liquid level and density measurement together with throttling devices. It converts the differential pressure signal into standard 4~20mA DC signal with HART/BRAIN digital communication. It supports local parameter setting and remote configuration, built-in static pressure secondary variable measurement function. It features 90ms fast response and excellent long-term stability, optional 0.04% high precision version. It obtains SIL2/SIL3 safety certification and various explosion-proof approvals. Widely used in petrochemical, power, metallurgy and water treatment process control loops.
